Google Analytics

Use the Google Analytics API

Actions84

Overview

This node integrates with the Google Analytics API, specifically targeting the Admin (V1Alpha) resource for managing Channel Groups. The "Update Channel Group" operation allows users to modify an existing channel group within a specified Google Analytics property. This is useful for organizations that want to customize or reorganize how their traffic channels are grouped and reported in Google Analytics.

Common scenarios include:

  • Updating channel grouping rules to reflect new marketing channels.
  • Modifying existing channel group metadata or definitions.
  • Maintaining consistent channel group configurations across properties.

Example use case:
A marketing analyst wants to update the definition of a channel group to better categorize traffic sources after launching a new campaign. Using this node, they can programmatically patch the channel group configuration without manual changes in the Google Analytics UI.

Properties

Name Meaning
Property ID The identifier of the Google Analytics property where the channel group exists.
Channel Group ID The unique identifier of the channel group to update.
Query Parameters Optional parameters such as updateMask (fields to update), filters, pagination, etc.
Request Body JSON object containing the updated data for the channel group.

Details on Query Parameters options (relevant ones):

  • updateMask: Comma-separated list of fields (in snake_case) specifying which fields to update.
  • Other query parameters exist but may not be relevant for this operation.

Output

The output is a JSON array containing the response from the Google Analytics API after updating the channel group. The structure corresponds to the updated channel group resource as returned by the API.

No binary data output is involved.

Dependencies

  • Requires valid Google Analytics API OAuth2 credentials configured in n8n.
  • Uses the Google Analytics Admin API v1alpha endpoint (https://analyticsadmin.googleapis.com/v1alpha).
  • The node expects the user to provide necessary identifiers (Property ID, Channel Group ID) and the request body with update details.

Troubleshooting

  • Missing Credentials Error: If the node throws "Missing Google Analytics API Credentials," ensure that OAuth2 credentials for Google Analytics API are properly set up in n8n.
  • Required Parameter Missing: Errors like "Property ID is required" or "Channel Group ID is required" indicate missing essential inputs; verify all required IDs are provided.
  • API Call Failures: Errors returned from the Google Analytics API will be wrapped and shown with the message prefix "Error calling Google Analytics API." Check the error message and stack trace for details.
  • Invalid Update Mask: If the update mask does not match the fields in the request body, the API may reject the request. Ensure field names are correct and in snake_case.
